Adding more strips in one code #im really new to this

Other Hardware LEDs and Multiplexing

hey guys so i found this code on the internet but i tried to add more strips i commented it out but keeps getting errors could anyone help please.

where can i put the code so u guys can help me

Read the forum guidelines to see how to properly post code and some good information on making a good post.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.

Along with the code we need to know the exact LED strips that you have, the Arduino board that you are using and how the LED strips are connected and powered.

Please post a wiring diagram. Written descriptions are always more ambiguous than a drawing. Hand drawn, photographed and posted is fine. Include all pin names/numbers, components, their part numbers and/or values and power supplies.

ok i posted it im using a arduino uno with ws2812 neopixels with the adafruit library

5

so ive got 3 strips strip stripa and stripb so im not sure how to add them all cause i need all 3 strips to work together

You seem to have ignored the part about posting code properly.

Post all the code. Post the code in code tags. Post the code without all of the extra " " crap.

i still struggle lol im new on the sitre to code and to everything lol let me try

where can i find the guidlines on how to post code

I am not that familiar with the NeoPixel library but I do see the following:

The show function should come after clear. The clear function writes to the pixels then the show function outputs what was written.

Same with the setLightsToColour function. Use the for loops to set the colors in pixel memory then show to display the colors.

What does that code actually do? How is that different from what you want?

Ok well when i uncomented the comments the other strips on the pins didnt work so somehow it got pixed when i pressed ctrl+t now al 3 strips work sl. So what it does is it runs from the last picel to the fist pixel in a faded way from bright to dim. Now i was wondering how to get a gap between the different strips so that they wont run along with each other
